Mattress Firm Promo Codes & Black Friday Sale

1. Buy in the Black Friday sale by December 8

   Up to $700 off select mattressesLow effortAnyone buying a mattress this fall

   The Black Friday sale runs October 21 to December 8, 2026, in stores and online. Its lead deal prices a select king at the regular price of a queen, or a select queen at the regular price of a twin, saving up to $700; on November 2, 2026 the sale also showed select mattresses in any size from $249.99 and a $499.99 queen mattress and adjustable base bundle. Clearance and outlet items and brands including Purple, Tempur-Pedic, Stearns & Foster, Beautyrest Black, Nectar and DreamCloud sit outside the up-to-$700 deal. Mattress Firm's 2026 releases show the same up-to-$700, free-base and Instant Gift deals at its Presidents Day, Memorial Day and summer sales too.^{[1, 2, 3, 23, 24, 25]}

2. Add the free adjustable base code

   Sleepy's Basic base, $299.99 valueLow effortSelect queens from $499, kings from $599

   The site's fine print, read November 2, 2026, gives a free Sleepy's Basic adjustable base with select mattresses: a queen base at a $499 minimum and a king base at a $599 minimum, in the same size as the mattress, and the October 21 release dates the deal through December 8, 2026. The Black Friday page says to enter the code at checkout, and one product page also offered $299 off an upgraded base instead. The fine print leaves out Purple, Serta iComfort, Tempur-Pedic, Stearns & Foster, select Sealy Posturepedic, Beautyrest Black, Nectar, Kingsdown Wesley and select DreamCloud beds, and the Black Friday page's FAQ also names tulo, Sealy Hybrid, Tuft & Needle, Lull and clearance items. The simplest check is the free-base line printed on a qualifying listing.^{[1, 2, 3, 5]}

   1. Filter the Sale & Clearance page to Free Adjustable Base.
   2. Pick a qualifying mattress and a base in the same size.
   3. Enter the code shown on the listing at checkout.

3. Use a brand gift code on a premium bed

   $300 on two brands, $200 on SealyLow effortTempur-Pedic, Stearns & Foster and Sealy buyers

   On November 2, 2026 the Instant Gift page gave a $300 instant credit toward select adjustable bases with a qualifying Tempur-Pedic or Stearns & Foster mattress, and a $200 credit with a qualifying Sealy mattress. Each brand has its own code, which has to be in the cart. The October 21 release dates these gifts through December 8, 2026, and unused value is lost, so put the base on the same order as the mattress. The fine print says the credit works on "a range of sleep system products" while the Instant Gift page names adjustable bases, so confirm it in the cart before you pay.^{[1, 3, 4]}

4. Verify with ID.me, or join the email list

   Extra 20%, or 15% on a first $699+ orderSome effortVerified groups, or first-order shoppers

   On November 2, 2026 the discount pages gave service members, veterans and their families, college students, teachers, first responders, medical workers and staff of participating employers a single-use code through ID.me: an extra 20% off qualifying purchases, taken from the listed price including sale items, with a new code available every 90 days. The email page offered an extra 15% off a first order of $699 or more for joining the list. Neither works with another coupon, both leave out brands such as Tempur-Pedic, Stearns & Foster, Beautyrest Black and Nectar, and the ID.me code also can't join the free adjustable base offer, so pick the one worth more to you. The ID.me pages offer an extra 10% off Purple and also list Purple under their exclusions, so ask a Sleep Expert before counting on that.^{[6, 7, 8, 9, 10]}

   1. Open your group's discount page from the site footer.
   2. Choose Verify with ID.me and follow the steps.
   3. Use the single-use code online or in a store.

5. Claim the Low Price Guarantee after you buy

   The price difference for 120 daysSome effortBuyers of a mattress set

   Mattress Firm says it will match any advertised price, including its own. If the same or a comparable mattress set is advertised below your invoiced price within 120 days of purchase, bring the ad to a store and it will credit your account or mail a refund check for the difference. That makes it worth watching prices after you buy, Mattress Firm's own included. Clearance items, floor samples and auction sites such as eBay, Craigslist and Facebook Marketplace are excluded.^{[11, 12]}

   1. Keep your invoice and note the 120-day date.
   2. Save the print or online ad with the lower price.
   3. Take the ad to a Mattress Firm store.

6. Check clearance and outlet for deeper cuts

   Up to 70% off select clearanceSome effortShoppers fine with no trial or warranty

   On November 2, 2026 the homepage showed up to 70% off select clearance mattresses, and the Mattress Outlet & Bedding Sale listed 117 items. The trade-off is in the policies: clearance, outlet and preowned items fall outside the 120 Night Sleep Trial, and the warranty page says they carry no warranty from Mattress Firm or the manufacturer. FirmCare sells protection plans for outlet products, with an outlet mattress listed from $69.99 for one year on the same date.^{[1, 12, 20, 21, 26]}

7. Finance at 0% or take 3% back with the card

   0% for 36 to 72 months, or 3% backSome effortApproved cardholders

   The Mattress Firm Synchrony HOME credit card offers 0% interest with equal monthly payments: on November 2, 2026 the in-store minimums were $1,499 for 36 months, $2,499 for 48, $2,999 for 60 and, through January 19, 2027, $4,999 for 72. Through the same date, select plans pay 3% back on a Visa Prepaid Card: 6, 12 or 24 months on $1,999 or more, or 48 months on $4,999 or more, at stores or by chat or phone. The rebate form is due by February 19, 2027, and the card's funds expire 6 months after it's issued.^{[1, 15, 16]}

Mattress Firm prints its public codes on its Black Friday sale page, its Instant Gift page and product listings, and we list those, with the end date where it gives one. A homepage banner shows a further code that changes from visit to visit, so it isn't listed. ID.me group codes are single-use and the first-order offer comes with the email sign-up, so the guide explains them instead of listing them.

1. A return takes back the free gift's value

   The fine print read November 2, 2026 says adjustable bases can't be returned and takes the base's $299.99 price off your refund if the mattress goes back; the Black Friday page's FAQ says up to $499.99. Instant Gift value, up to $300, comes off in the same way, and the returns page charges for any Gift With Purchase item on a cancelled or returned order.^{[1, 2, 12]}

2. A free base can bring a delivery fee

   On November 2, 2026 the delivery page said a fee of up to $159.99 applies when you buy an adjustable base during the Free Adjustable Base promotion. Check the delivery line in your cart so you can weigh it against the base's value.^[13]

3. Many items sit outside the sleep trial

   The trial doesn't cover clearance, outlet or preowned items, floor and display samples, pillows, mattress protectors, furniture, accessories, or adjustable bases other than TEMPUR-ActiveBreeze Smart Bed bases. Special order sizes such as California King, Split Cal King, three quarter, crib and futon are final, though the two California King sizes stay eligible in California.^[12]

4. Shorter card plans can charge interest from the purchase date

   On 6-, 12- and 24-month plans, interest is charged from the purchase date if the balance isn't paid in full in time, and the minimum payments may not clear it. The fine print read November 2, 2026 put the purchase APR at 34.99% for new accounts as of July 31, 2025. In-store 60- and 72-month plans need taxes and delivery fees paid upfront.^{[1, 16]}

5. Compare-at and store prices can differ

   Mattress Firm's Legal Disclaimer says compare-at prices reflect nationally competitive MSRP and list prices and don't reflect interim markdowns. It also says selection and prices may vary from store to store, so check your local store and the site before you pay.^[22]
